c. Calculate the magnitude of the electric force on D from A. d. Calculate the magnitude of the electric force on D from B.e. Which force is larger? Was your answer in part b correct? f. In the tug-of-war of forces on D from charges A and B, which is the more important factor: that A has a greater (magnitude) charge than B, or that B is closer to D than A? g. Calculate the net electric force on D from A and B. Is this net force attractive or repulsive?3. Charged objects can attract neutral matter through the polarization of the neutral matter - pushing the parts that have the same electric charge slightly further away. At the molecular level, neutral molecules with separated parts that are positive and negative can also attract one another by orientins properly. One example of this is hydrogen bonding of water molecules. This is the primary mechanism that creates surface tension in water, and a similar phenomenon plays a big role in a variety of biochemistry. The two hydrogens in a water molecule are positive, each with a charge te, and the oxygen is negative, with a charge - 2e (e - d 2d OE 1.602 x 10-19 C). Here we will explore the electric forces between A -OB D water molecules. The angle between hydrogen atoms in a water molecule is actually 104, but for simplicity we'll treat it as if it were a OF right angle, 90. A sketch of how the water molecules are aligned in a CO water-water hydrogen bond is shown here. In a single water molecule, the distance between the oxygen atom and a hydrogen atom (the distance between A and B labeled d) is about 96 pm (1 pm = 1 x 10 12 m). The distance between the water molecules (the distance between B and D labeled 2d) is about twice as far: 192 pm. (Note: k = 8.99 x 109 N . m/C2) Let's consider the electric forces on the DEF molecule. We will start by considering the "backbone" of the hydrogen bond composed of charges A, B, and D
